Barnes and Noble just posted a notice informing customers that PIN pads in 63 stores across the country have been tampered with. The compromised PIN pads could have recorded your PIN number. Not good. If you've shopped at a brick and mortar Barnes and Noble over the last couple of months, keep a closer watch on your credit card statement and maybe even change your PIN.

Barnes and Noble launched an investigation last month when employees reported a malfunctioning unit. After inspecting 7,000 devices at 700 stores across the country—every PIN pad in every store—B&N determined that the 63 units showed evidence of tampering. The affected stores are in California, Connecticut, Florida, Illinois, Massachusetts, New Jersey, New York, Pennsylvania, and Rhode Island. Check out the Barnes and Noble announcement for a complete listing of every affected store. Here's hoping nobody loses their pay day to this scam. [Barnes and Noble via WSJ]
